The adaptable and efficient infrastructure for popular information provision and utilization is very important in the distributed information service system. In this paper, we introduce a rating oriented distributed information system sustained by push/pull mobile agents to cope with the rapidly changing of providers and users' requirements. Based on this environment, an autonomous information allocation technology is proposed, to put the most popular information near to users. Moreover, when users' demands change, an autonomous information reallocation technology is proposed to achieve load balancing and guarantee that users can always get the information from a certain pathway. We proved the effectiveness of the proposed system through the simulation and comparison with the conventional system. Moreover, advantages through applying autonomous information reallocation within the system is quantitatively shown.
